In 2011, Oriana Sousa, a Portuguese psychologist who is now 28 year-old was diagnosed with a rare form of ovarian cancer. When the symptoms started doctors initially failed to diagnose the cancer. For several months Oriana suffered from frequent constipation and fatigue. She was also thirsty all the time. Then she started to have terrible abdominal pain and began vomiting. Her doctor told her she was fine and she shouldn’t worry. Her aunt who is a nurse recommended that she see visit another doctor. The new doctor performed a CT scan and found a massive tumor. Oriana was diagnosed  with a very rare, aggressive and fatal form of ovarian cancer.
